Six of the 13 Hudson County public school districts have reopened, but others, including Jersey City and Bayonne, remain closed because of the power outages related to Hurricane Sandy.

“We can’t send our students into schools that have no electricity and heat," Jersey City Mayor Jerramiah Healy said in a statement. “This status is very fluid. As electricity is restored throughout the city we will update everyone as to the restoration of regular school scheduling the return of full services.”

Schools districts that are open are North Bergen, Weehawken, West New York, Guttenberg, Harrison and the Hudson County Schools of Technology.

Besides Jersey City, schools are closed in Union City, Bayonne, Hoboken, Secaucus, and Kearny. East Newark school officials could not be reached and calls to town hall were not answered.
